- removed from the record sheet.

for when it is employml to do all of theinldng upon the record sheet, the rec rd sheet is not liable to be Hooded or blotted by the ink, this objection being commonly attendant upon the operation of recording instruments of the prior art, particularly when the marl:- ing devices of such prior instruments are permitted to contact too long Witlrone spot on the record sheet and are brought into contact too often with the same spot of the record sheet. By the use of the wicldng of my invention, the flooding or blotting is entirely eliminated and the pen can operate continuously at one place upon the record sheet Without flooding the same with ink or making the spot materially larger than that which would be obtained by a single touch of the marking device on the record sheet. Furthermore, by the use of the Wicking, par ticularly when such wicking is composed of substantially parallel strands of thread, the capillary action is such as to enable said. wiclring to contain at all times just enough ink to provide the necessary marking. With other forms of marking devices, there is much trouble to contend with when the ink used is or" diflerent densities; that is, if the ink by chance should be too thin, it is liable to flow out upon or flood the pa er, and if too thick, the markings are liab e to stop alto ether. The markings made by the manning device of my invention, are free of trouble due to inks of. different densities. By reason of the Wicking being at all times wet, owing to capillary action, the marking is made ossible no matter how light the touch wit 1 which the marking device is applied to the record sheet. 'Vl hile the wicking is always Wet, With the attendant advantage last stated, yet the extent to which the Wicling is Wet is automatically limited to avoid blotting action, this characteristic being very important, as a great range of demand is made upon the ink needed in recording a Widely fluctuating load or a steady load.

In common With. recording instruments that have long been known, the marking device is applied to the record sheet intermittently. In the apparatus of my invention, the. marking device is intermittently a plied to the record sheet by means of an e ectro' magnet g having an axis coincident with theaxis of the shalt a and cooperatively related with the disk-shaped armature h which is preferably inter osed between the magnet The armature carrying end of the intermediately pivoted arm f is slightly more burdened than the other end of the arm, so that when the electro-magnet g is deenergized the armature end of said arm f is allowed to descend and rest upon a, stop 1', the pen then being The armature is shown in an attracted position in Fig. 3 and in an unattracted position in Fig. 1.

ceases The full flux of the operating magnet acts upon the arinafture h at all positions ol the marking device, which is due to the (U-:1Xl:ll arrangement of the magnet and its armature with respect to the shaft u,'l'or it will be seen that no matter in what position the marking device may be placed, the relative position of the armature and the magnet is not changed. I

In prior devices, the electro-maguets em ployed for applying the marking elements to the record sheets were similar to sections or sectors cut from circles having diameters of twelve or fifteen inches and having cores of U shape about a half inch deep. The coil of each of such magnets was bound upon one of the limbs of the U-shaped core and required about six ounces of wire, with the consumption of about one-half ampere to operate the magnet. The magnet g included in the re cording instrument of my invention takes a small fraction of a watt to operate it-and is only about one-twentieth ol' the weight'ol' the. corresponding magnet ol the prior art. Furthern'iore, the attractive force upon the armature in. the apparatus of the prior art varied at di."erent places along the face of the magnet, due probably to the fact that the magnetism of such prior magnet concentrated at the extreme ends or corners of the magnet and became Weaker at the center of the magnet, all of these factors being liable to secure uneven operation of the'instrunient. In the device of my present invention, the small ironclad electro-niagnet 1 is very efficient,

because of its alinement- With the operating shaft a and its location of less than an inch from the shaft carrying the marking device. By simply drawing up the armature one-- thirty-second of an inch, the inking" end of the marking device travels in moving toward the record sheet, through a distance of about oneeighth of an inch at all'times irrespective of the angular deflection of the shaft a and l the marking device, while at the same time equality of the attractions of the armature is always assured no matter upon What part of the record sheet the marking device may be Working, for the reasons Which have been stated. In short, the armature attached to the pen of a recording instrument of the prior art passed over about SIX inches of surface from one end of the drawing magnet to the other, being attracted during its travel With varying degrees of force, Whereas in the re cording instrument of my invention, the armature is attracted by the same area of pole at all times. c Fig. 6 illustrates diagrammatically a lamiliar system for controlling the operation of the marker applying magnet g and the travelpf the record sheet n, there being indi cated in Fig. 6 the-clock mechanism s for intermlttently closing a circuit at t, Which circuit includes a battery u, the electro-magnet g and thc rccord shcct the arrangcmcnt diagramnmtn ally indiratcd in Fig. 6 will hc wcll undcrstood in thosc sliillcd in thc art. l will not dcscrihc ii further.
